Part 3: What Is AI Upscaling And How Does It Work?

AI upscaling enhances blurry, low-resolution images by enlarging them and preserving natural details instead of just stretching. It's like an expert who has studied and memorized countless images.

While it doesn't create its own original works, it steals and combines details from other people's images like a thief. Even the most blurry color blocks can be identified by AVCLabs Photopro AI as a ray of sunlight. A blurry face can be precisely enhanced with details such as the nose, eyes, and mouth.

AI image upscaler intelligently fills in the gaps, rather than simply filling in like in Photoshop. For example, AVCLabs Photopro AI carefully examines your image, identifying blurry lines and lost details. It can enhance the texture of leaves and grass in a blurry landscape photo, and add clearer eyelashes and hair to a blurry portrait. Traditional image upscaling, on the other hand, simply duplicates the same pixel four times.

After the drawing is completed, AVCLabs Photopro AI will perform a final check, erasing unnatural imperfections. For example, it will remove jagged edges and halos that often appear when the image is enlarged. It makes the final high-resolution image look clear, clean, and natural, just like it was originally a high-resolution photograph.

FAQs About AI Image Upscaler

Is an online AI image upscaler safe for private photos?

Private photos are highly sensitive, so we recommend using AVCLabs PhotoPro AI. It's a local desktop version, so there's virtually no risk of uploading. You can also check the privacy policy of any AI image upscaler before using it to see if the photos are encrypted, etc.

What kinds of images work best with AI upscaling?

When using AI to enlarge images, not all types of images will yield the same results. For example, landscape photos, architectural photos, and illustrations—images with clear textures, patterns, or edges. Images with a lot of text and graphics, such as logos, will also benefit more. AI enlargement can better enhance these image details. However, it can also improve images with very low resolution or heavy compression, but the effect may not be as good as for slightly blurry images.

What image formats do AVCLabs AI image upscaler online free support?

It supports input formats: PNG, JPG, JPEG, BMP, JFIF, and WebP. AVCLabs PhotoPro AI also supports a wide range of image formats, ensuring compatibility with most photos users upload. It works smoothly with common formats such as JPG, JPEG, PNG, BMP, JFIF, WEBP, etc.
